Aliasing gemstone → gem
Link to alias
More suggestions:
Having specific gemstone types doesn't make sense for tagging since many of them can be different colors. For example, diamonds, sapphires, and topaz can all be a variety of colors.
I suggest we switch to using (color)_gem instead. This makes tagging/searching easier too (one does not need to know an amethyst is purple to tag/search for a purple gem, for example).
(color)_jewel/s, (color)_gems -> (color)_gem
(color)_gem -> gem (implication)
The gemstone types themselves need disambiguation. Although in reality some gemstones can be different colors, this doesn't necessitate disambiguation on its own since they will almost certainly be tagged for their most well known color. However, many gemstone types are used as character names as well.† For this reason, I think it would be better to disambiguate.
Alias to either gem_(disambiguation) or *_(disambiguation):
diamond
emerald
ruby
sapphire
pearl
quartz
opal
amethyst
topaz
Plural forms can maybe be aliased directly to (color)_gem. If you want to be extra thorough, see the gem encyclopedia.
Diamond could also mean ♦ so maybe it should have it's own disambiguation even if other gems don't.
†Some characters already use their own _(...) tag, but some still need to at least be sorted into a _(character) tag.
